C Correct answer
Explanation

Car P speed = 66 kmph. Distance P = 66 * 11 = 726 km. Car Q distance = 726 + 242 = 968 km. Car Q speed = 968 / 11 = 88 kmph.

AI explanation

Using the formula Distance = Speed x Time, the distance covered by car P is 66 x 11 = 726 km. Car Q covers 242 km more in the same 11 hours, so its total distance is 726 + 242 = 968 km. Using the formula Speed = Distance / Time, the average speed of car Q is 968 / 11 = 88 kmph. The result is 88 kmph.
